Despite a lack of VC funds, there’s a steady flow of entrepreneurs. The entrepreneur started investing in water tech startups a few years ago. A small fraction of venture capital dollars currently goes into tech to manage or clean water.

It will take decades to slow nitrate contamination in groundwater from industrial agriculture in parts of the state of California, so communities are taking matters into their own hands to get clean drinking water.

Decades after declaring 1,2,3-TCP a carcinogen, California is finally regulating the toxin. But the cost of remediation will be high and communities are turning toward litigation to pay for water treatment.

Decision time is approaching for the agencies that will have to pick up the nearly $17-billion tab for building two massive water tunnels under the Sacramento-San Joaquin Delta, the heart of the state’s water works.

East Porterville was the hardest-hit community during the drought, when nearly 1,000 people were without water. Efforts to find a long-term fix have been successful but came with a big price tag and some important lessons.

The Environmental Protection Agency has so far found perchlorate in 45 states, tainting water supplies of roughly 16 million Americans. Yet, there is no mandate that water utilities outside of California and Massachusetts test for the toxic chemical or let residents know when it’s in their tap water.

Drought conditions continue for thousands of rural residents in the San Joaquin valley who rely on groundwater. And the race to dig deeper wells is a losing game for small communities and those on private wells.

Rita Sudman is longtime observer of the California water, and even led the Water Education Foundation. In 2016, she co-authored "Water: More or Less." In an interview with ABC10, Sudman talked about her book and the future of California's water policy.

More than 1 million people in the region have been exposed to unsafe drinking water in recent years from pesticides, arsenic, nitrate and uranium. And many communities also face multiple environmental health threats.

Do people only care about water during extreme drought, like California’s recent one? It turns out most Americans care a lot about water and have strong feelings on infrastructure spending and other water-related issues.

There is so much water in the state’s vast plumbing system that for weeks, the big government water projects have reduced exports from the Sacramento-San Joaquin Delta. Yet there is more room than ever in one of the state’s most capacious storage spaces: the San Joaquin Valley aquifer.

In the Central Valley of California, hundreds of wells that provide water to a million people are tainted with a chemical that some experts say is one of the most powerful cancer-causing agents in the world. The state is poised to take the first step Tuesday to regulate the substance — called 1,2,3, TCP — but test data compiled by an activist group show it's also been detected by utilities across the country.

California has much more potential to store water underground in aquifers than in surface reservoirs. The state should be focused on this opportunity for future years, writes scientist Mohammad Safeeq.

Tulare Lake is gone (although it makes a partial reappearance during very wet years like this one), but what the California Department of Water Resources now dubs the Tulare Lake Hydrologic Region is the most productive agricultural region in the state -- making it, by extension, the most productive agricultural region in the U.S. and probably the world.

The degree of pollution of rivers resulting from human activities is assessed using different biotic indices. The latter reflect the ecological status of a river based on the quantity and diversity of organisms selected as bioindicators, due to their ecological preferences and tolerance to pollution.

Millions of homes across the state are connected to water sources contaminated with a cancer-causing chemical called 1,2,3-Trichloropropane (TCP) and until recently, few Californians knew about it, let alone had any way to fight it.

A new poll finds Americans are more concerned about their drinking water than they are about any other environmental issue. Drinking-water scares like the lead contamination crisis in Flint, Michigan, appear to have had a lingering impact on Americans’ concerns with their drinking-water supplies.

This article helps Californians identify their source(s) of drinking water, learn more about how drinking water is treated, and learn how to help prevent pollution of our groundwater and surface water supplies.

California is expected to set a strict state-level maximum contaminant level for a probable human carcinogen ― 28 years after the state’s Water Resources Control Board first detected the chemical in its drinking water system.
